The atomic number is the number of protons.
you look at either the atomic number or the number of electrons. That's the number of protons.
It is the number of positely charged nuclear particles ( protons ).
protons plus neutrons = atomic number
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
the atomic mass number is the number of protons/electrons in an atom
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
First, find its atomic mass on the periodic table and subtract the number of protons (element number) from it and there you go
equal to number of protons
It is not something you calculate. The number of protons in an atom can be determined by looking up its atomic number on the periodic table. In the case of silicon, the atomic number is 14, so it has 14 protons.
The atomic number (1 to 114) in the periodic system is equal to the number of protons.
